Our Research Overview and Studies Overview activities are centered around the architecture of computing systems: From hardware over system software up to languages and compilers with a focus on constructive methods for the design and development of adaptable and versatile system software. The group is led by Prof. Daniel Lohmann.
Those machines that are closest to our everyday life are special-purpose systems embedded into the physical world. Due to this embedding, we know a lot about the surroundings of a system. We exploit this knowledge in the design of hardware and system software.
The requirements for every system are special. However, we often favor unspecific general-purpose components over special-purpose solutions. With the techniques of automatic tailoring, we can achieve specialized systems at moderate development costs.
During the architectural design, the required functionalities are often well understood. Nonfunctional aspects are decisive for choosing a system for a given task. Especially for embedded systems, we can optimize various aspects towards the given application scenario.
